CORDING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 653,403, dated July 10,1900.

Application filed July 20, 1899. Serial No. 724,524. (No model.)

To all whom it may concern.-

Be it known that I, GEORGIANA ROBINSON, a citizen of the United States,residing at Orange, in the county of Essex, State of New Jersey, haveinvented certain new and useful Improvements in Cording Attachments, ofwhich the following is a specification, refer ence being bad therein tothe accompanying drawings.

This invention relates to cording attachments, and particularly to anattachment adapted for application to sewing-machines and to produce aproduct in which the cloth is tightly drawn about the cord and thestitching concealed from View.

The invention has for an object to provide an improved construction oftubular guide and feeder for disposing the cloth over the cord andholding the same in proper position for stitching.

A further object is to locate this guide relative to and in combinationwith a holdingfoot and needle to insure the stitching in such positionthat the same will be effectually concealed in the finished product andthe cloth tightly held about the cord.

A further object of the invention is to provide an improved mounting forthe guide whereby the same can readily be removed from thesewing-machine or adjusted in relation to the holding-foot wheneverdesired.

Other objects and advantages of the invention will hereinafter appear inthe following description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan of the invention in'use. Fig. 2 isavertical section on the line 2 2 of Fig. 1. Fig. 3 is an enlargeddetail section upon the same line. Fig. 4 is a detail perspective of theguide and its adjustable holding-plate. Fig. 5 is a similar View of thefoot; and Fig. 6 is a vertical section through the finishedproduct,showing the disposition of the stitching beneath the cord.

Like letters of reference indicate like parts throughout the severalfigures of the drawin s.

in the drawings the letter A designates the table or other foundationupon which the cording attachment is secured, which in most cord toproduce an ornamental effect.

instances will be the work-plate of a sewingmachine. For the purpose ofillustrating the operation of this invention certain detail parts ofsuch a machine have been shown,

; such as a presser-foot B, adjustably secured upon a rod B by means ofa set-screw B and a needle 0, operating at one side of said foot. Thepresser-foot, as usual, operates in conneetion with any suitable form offeed-plate 1 B to produce the feeding action of the goods.

The tubular guide D is composed of a taperin g cylinder having thelongitudinal slot D, extending in a substantially-parallel line with thebase D of the plate. It will be seen that the .taper of the tubularguide D compresses thecord to a slight degree and also folds the clotharound the same, so that when the corded cloth emerges from the guide itis tightly drawn about the slightly-compressed cord, at which time thestitching action occurs, and the cord afterward expands slightly tocompletely fill the loop in the cloth and bring the line of stitching 0directly beneath the cord, as shownin Fig. 6. To accomplish this objectto the best advantage, I have found it necessary to locate the needle 0directly adjacent to the side of the tubular guide D and at one side ofthe presser-foot B, which exten ds substantially parallel with thedelivery end of the tubular guide. This presser-foot beyond the end ofthe guide 1s disposed at an angle to a straight line extending from theneedle in the direction of the line of feed, so as to slightly free thegoods and permit an easy movement of the same beyond the point ofstitching, whereby an operator may shirr or gather the cloth uponl til e1s gathering of the cloth upon the cord requires that the cloth shouldin no instance be stitched to the cord, and the particular dispositionof the needle 0 herein disclosed is adapted to always carry thestitching beyond the edge of the cord, (see Fig. 3,) and thus permit thegoods to be moved or gathered upon the cord Without difficulty. Thepresser-foot is shown in Fig. 1 as slightly turned at an angle to astraight line extending from the needle in the direction of the line offeed; but it is obvious that the same result may be obtainedby varyingthe width of the foot itself.

The tubular guide D may be secured in position in any desired manner;but a very efficient method of accomplishing this result is by means ofa slot D formed in the baseplate D and adapted to engage projectingflanges E, extending upward from an adjust-- able plate E. This platemaybe held in position by means of a set-screw E and adj usted throughthe medium of a slot E beneath said screw, as shown in Fig. 2. Thisadjustable mounting permits the removal of the tubular guide and itsreplacement by a difierent size when desired and the further adjustmentof the plate E to accommodate any class of work, while the guide and itsholding-plate can readily be removed whenever it be desired to use thesewing-machine without such attachment.

It is believed that the operation of the invention will be apparent tothose skilled in the art, and it will be seen that in the presentstructure it is not possible to stitch through the cord, as the needleworks ilh mediatel y adjacent to the edge of the funnel, disposing thestitch close to the edge of the cord, so as to conceal the thread in thefinished product, as shown in Fig. 6. This structure also permits amovement of the cloth upon the cord for any desired purpose, as beforesuggested. The guide can also be advantageously used for piping or foldsby bringing the cloth to a round fold within the guide and thenstitching without the cord or with the cord and afterward removing thecord. It is obvious that to obtain the most advantageous results of thischaracter a tubular tapering guide is essential and that such aguideshould be substantially circular at all portions of its length and notflattened. The location of the guide upon the base-plate of the machineprevents all swaying or other motion which occurs in cording devicescarried by the presser-foot, and the relative position of the guide,work, and needle are always true and uniform. The disposition of thepresser-foot brought close to the needle gives pressure and support tothe work on the side opposite to the guide, so that in the presentinvention the work is positively held and controlled during thestitching action, and the angular disposition of the face of the footnext the guide allows the goods more freedom in emerging from the guideand does not disturb the straight line of travel. The method ofattaching the guide to the base-plate is also believed to beparticularly advantageous, as it can readily be removed and replacedwithout the necessity of using a set-screw, and this economizes the costof construction as well as simplifies the same.

It is obvious that changes may be made in the details of constructionand configuration without departing from the spirit of the invention asdefined by the appended claims.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a cording attachment, a base-plate provided with a taperingtubular guide located upon its upper face and within the edge thereofand having a longitudinal edge at its lower portion extending parallelwith and above the edge of the base-plate; substantially as specified.

2. In a sewing-machine, the combination of a cording attachmentcomprising a base-plate having on its upper face a tubularguide provided with a longitudinal slot, stitch-formin g mechanism including aneedle located immediately adjacent to the delivery end of said slot,and a p resser-foot disposed substantially parallel to the delivery endof said slot; substantially as specified.

3. In a sewing-machine, the combination of a cording attachmentcomprising a base-plate having on its upper face a tubular guideprovided with a longitudinal slot, stitch-forming mechanism including aneedle and feeding means located immediately adjacent the delivery endof said slot, and a presser-foot located at one side of said needle andhavinga face disposed at an angle to the direction of feed from saidneedle; substantially as specified.

4. A cording attachment for sewing-machines comprising a base-platehaving one of its edges curved back upon itself to form a taperingtubular guide within the edge of the base-plate and having alongitudinal edge parallel with and above the bent edge of saidbase-plate; substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGIANA ROBINSON.
